# AccountId and ChannelId

> Learn how AccountId and ChannelId changed in the upgrade.

Various functions in the VivoxVoiceChat module are replaced by functionality in [AccountId](../../reference-manual/unreal/class_account_id) and [ChannelId](../../reference-manual/unreal/class_channel_id). For more information about AccountId, see [Sign in to a game](../vivox-unreal-sdk-basics/sign-in-to-game). For more information about ChannelId, see [Join a channel](../channels/join-channel).

The following list provides the name of the function in the VivoxVoiceChat module, the comparable function in VivoxCore, and supplemental information for completing a version switch.

> **Note:**
>
> The URI-related methods in this section are not typically required for a VivoxCore integration, but they can provide additional control and functionality beyond what VivoxCore does with them by default.

* CreateAccountName(const FString& PlayerName) is replaced by `AccountId(const FString& issuer, const FString& name, const FString& domain, const TOptional<FString>& displayName, const TOptional<TArray<FString>>& spokenLanguages)`

  * The `VivoxClientApi::AccountName` structure is replaced by the AccountId structure, and requires additional parameters to connect to the correct VivoxCore server. This is primarily the issuer and domain, although you can also add a DisplayName to display to other users and a list of SpokenLanguages.

* `GetPlayerNameFromAccountName(const VivoxClientApi::AccountName& AccountName)` is replaced by `Name()`

  * Calling AccountId::Name() on the AccountId in question returns the FString Name that is stored within the AccountId.

* CreateUserUri(const FString& PlayerName) is replaced by `ToString(), AccountId(const FString& issuer, const FString& name, const FString& domain, const TOptional\<FString>& displayName, const TOptional\<TArray\<FString>>& spokenLanguages).ToString()`

  * User URIs within VivoxCore are generated and handled entirely within the AccountId framework.

    * Create an AccountID from a URI by using `AccountId::CreateFromUri(const FString& uri, const TOptional<FString>& displayName)`.
    * Turn a constructed AccountID into a URI by calling `ToString()`.

* `GetPlayerNameFromUri(const VivoxClientApi::Uri& UserUri)` is replaced by `AccountNameFromUri(const FString &uri)`

  * Because `AccountId::AccountNameFromUri(const FString &uri)` calls `AccountId::CreateFromUri(const FString &uri).Name()`, the most effective way to hold on to the AccountId as a whole is to use `CreateFromUri(const FString &uri)`, then store the result and call Name() on it.

* `CreateChannelUri(const FString& ChannelName, EVoiceChatChannelType ChannelType, TOptional<FVoiceChatChannel3dProperties> Channel3dProperties)` is replaced by `ChannelId(const FString& issuer, const FString& name, const FString& domain, ChannelType type, Channel3DProperties properties)`

  * Similar to AccountIds, ChannelIds handle all of the static information storage for a channel, and is mostly comprised of all the aspects that make up a URI.

* `GetChannelNameFromUri(const VivoxClientApi::Uri& ChannelUri)` is replaced by `CreateFromUri(const FString& uri).Name()`

  * To pull the name from a URI, convert the URI into a ChannelId by using ChannelId::CreateFromUri(const FString& uri), and then call Name() on the resulting ChannelId.

* `GetChannelTypeFromUri(const VivoxClientApi::Uri& ChannelUri)` is replaced by `CreateFromUri(const FString& uri).Type()`

  * To pull the ChannelType from a URI, convert the URI into a ChannelId, and then call Type() on the resulting ChannelId.
